Your script is so useful man, thanks for sharing :)

I highly appreciate you script, but there is one severe problem making it (almost) unusable for me: It removes unrelated docker containers and images.
Somewhere I read the recommendation, to use the "legacy" iptables command instead of the version based on nftables, so I tried. Apparently these tables were never cleaned up. After running the script with "flush" iptables-save showed me a message "Warning: iptables-legacy tables present, use iptables-legacy-save to see them". Very hard to detect. Maybe it would be helpful to flush these tables as well?

Your shared shell script is effective. I was stuck on this issue for a long time and even asking GPT couldn't solve it. Thank you for sharing.
非常謝謝你~好用!
Thank you @superseb. Your script worked well
Careful with this as if the umount fails then it can potentially remove all the data in the Persistent Volume shares, IE ceph/NFS etc, probably worth adding some form of sanity check to make sure that the mount points inside /var/lib/kubelet have been successfully unmounted before performing an rm -rf on the directory
